Hi,
I am getting a lot of hits on my site which appear to be caused by a postback by a remote site. basically it appears that the attacker is sending a postback string to my page which is causing the error in the log. I have added a regular experssion to the textbox to stop direct entry but I am assuming that the attack is just a postback and does not flow through the page. Can anybody help me figure out how to avoid this type of attack? I am using IIS 7. Here is a copy of the log:
